Retinoscopy Lens Racks
The Retinoscopy Lens Rack is an organized holder for commonly used retinoscopy lenses, allowing fast, one-handed lens changes during objective refraction. It improves exam efficiency and accuracy by keeping lenses clearly visible, securely positioned, and immediately accessible at the chairside.

Occluder, Vision Therapy
Single Pinhole Occluder
Single Pinhole Occluder is a clinical diagnostic tool used during visual acuity testing to help determine whether reduced vision is mainly due to refractive error or possible ocular pathology. The small central pinhole limits peripheral light rays and allows the patient to view through a narrow aperture, often improving vision when refractive correction is required.

Vergence Facility Prism 12D/3D – Mounted
The Vergence Facility Prism 12Δ / 3Δ (Mounted) is a two-sided yoked-prism flipper that alternates base-out and base-in demand to train and measure vergence facility efficiently. It provides 12Δ BO (6Δ per eye) on one side and 3Δ BI (1.5Δ per eye) on the other—ideal for timed near drills and recording cycles per minute (CPM) in clinic or supervised home programs.

Flipper, Vision Therapy
Vergence Facility Prism Flipper 12D BO 3D BI
The Vergence Facility Prism Flipper (12Δ / 3Δ) is a two-sided yoked prism flipper that alternates base-out (12Δ total) and base-in (3Δ total) demands to train and measure vergence facility efficiently. Use it with a near target to run timed BO↔BI cycles and record cycles per minute (CPM) for quick baseline, progress checks, and home-program carryover.

Examination Tools, Maddox
White Maddox Lens for Trial Frames
The White Maddox Lens (for Trial Frames) converts a point light into a bright white line to quickly reveal and measure horizontal or vertical phorias/tropias during dissociated testing. It fits standard 38 mm trial frames and, used with a penlight and prism neutralization, delivers fast, repeatable prism-diopter readings at distance or near.

Yoked Prism 16 Pair
The Yoked Prism – 16 Pair (Flat) set provides sixteen matched prism pairs with the same power and base direction in both eyes, producing a controlled, symmetric field shift without adding fusional demand. Ideal for visual midline shift evaluations, posture/gait and spatial-orientation trials, and vision-therapy progressions, the flat, durable optics make quick chairside swaps and consistent observations easy.
